Chapter 900 Unreliable Speculations

In the unknown underground space, torches were inserted into the ground one by one, forming a long dragon like flames.

+10000

As the blue numbers above his head kept flashing, Xiao Han's face became more and more puzzled.

Gradually, a dark yellow rock wall blocked the way.

Looking back at the long dragon of flames behind him, he held up the torch and whispered softly: "This stone wall seems to have traces of artificial excavation."

"But why is there no trace of human activity here?"

As hundreds of torches were thrown out, although the full picture of this space could not be seen clearly, the traces of knife and axe chopping were very obvious on the ground and the rock wall.

Strangely, no tools belonging to humans were found, not even murals or stone carvings.

After walking more than a hundred meters in both directions, the blue numbers above his head did not continue to increase, so Xiao Han stopped immediately.

"I want to see what's going on."

Unable to resolve the doubts in his heart, he immediately stuck the torch into the ground, then immediately took out the explosive ore-crushing shovel, aimed at the stone wall in front of him, and smashed it down fiercely.

Dang!

With a crisp sound, the shovel in his hand was violently bounced away. Xiao Han showed a trace of wonder in his eyes, and whispered softly: "Oh my god, I can't dig it."

"This is a spiritual weapon-level shovel. It can break ores below level 12 with one blow!"

"It can even destroy the Demon Sealing Tower that sealed the Abyss Blood Emperor. I don't believe it here. The hardness of this rock wall is stronger than the meteorite stone."

As he said this, he waved the shovel again without hesitation, smashing it down at a crazy speed.

Dang! Dang! Dang!

A series of explosions sounded in his ears until a flash of fire appeared on the explosive ore-crushing shovel, and the dark yellow rock in front of him finally fell off with a click.

At this time, a system prompt sounded in Xiao Han's ears.

"Ding, you get a piece of Xuangang stone, triggering a hundred-fold reward, you get a piece of basalt."

Hearing that it was just a kind of rock he had never heard of, Xiao Han didn't care too much, but immediately looked at the gap that was dug out.

At this time, it can be clearly seen from the gap that a different color is revealed inside.

Just like gambling on stones, it reveals a very rare jade color.

Under the illumination of the torch, it reflects a dazzling light, and at the same time, it seems that there is a special breath escaping from it.

+20000

And almost at the same time, the blue number that appeared above his head doubled instantly.

"Fuck, what's going on?"

Reaching out and touching the jade crystal at the gap, Xiao Han's eyes flashed quickly, but he still didn't understand why.

But fortunately, it seems that he is very close to the answer.

Ignoring the basalt that fell on the ground, the explosive ore-crushing shovel in his hand swung quickly again.

Dang! Dang! Dang!

A series of explosions, a flash of fire appeared on the spiritual ore shovel again, and the passive special skill of ore crushing was triggered again, and another piece of basalt was knocked down.

But even so, the gap is still very small, and it is still a bit difficult to dig out the jade crystal.

But fortunately, the gap has been opened, and it is only a matter of time to dig it out.

Eager to solve the doubts in his heart, Xiao Han waved the explosive ore-crushing shovel faster.

Dang! Dang! Dang!

As the explosion sounded continuously in his ears, a ray of fire light appeared from the spiritual mining shovel from time to time, successfully triggering the ore crushing stunt, and also making the gap in front of him bigger.

Seeing this situation, Xiao Han's eyes flashed with expectation, and then the mining shovel in his hand aimed at the jade crystal and smashed it hard.

Ding!

At this time, the expected system prompt sound finally sounded in his ears.

"Ding, you get an energy crystal (level 3), triggering a hundred times reward, you get an energy crystal (level 5)."

Hearing such a prompt, Xiao Han's eyes were full of disbelief, and he whispered softly: "How is this possible, why is it an energy crystal?"

Although he said this, his eyes showed a touch of ecstasy, and the mining shovel in his hand waved even faster.

At this time, he already had a guess in his heart.

But this guess is really unreliable. He didn't think his luck would be so good that he could easily encounter such a thing.

Ding! Ding! Ding!

The dense and rapid explosions continued to ring in his ears. With the flames from the explosive ore-crushing shovel from time to time, the gap in front of him became larger and larger.

Until the diameter of the gap was widened to half a meter, Xiao Han immediately began to dig deeper energy crystals with all his strength.

Compared with Xuangang stone, the hardness of energy crystals is more than one level lower.

The spiritual mining shovel only dug casually for more than ten minutes, and easily dug out a cave with a diameter of more than two meters and a depth of more than one meter.

Nearly a thousand third-level energy crystals were collected, and Xiao Han was more certain of his guess at this time.

However, it was still just a guess. If he wanted to know whether he guessed wrong, he still needed to determine how big the mountain in front of him, which was completely made of energy crystals, was.

"Hey, the outermost layer is filled with level three energy crystals. Will there be any other changes inside?"

As he said this, Xiao Han showed a look of excitement on his face, and at the same time, he waved the explosive ore crushing shovel in his hand faster.

when! when! when!

With a crisp impact, he quickly dug deeper in almost a straight line.

Fifty meters, one hundred and fifty meters... three hundred meters...

As the depth continued to increase, the joy on Xiao Han's face became more and more intense, and he whispered softly: "As long as the length exceeds five hundred meters, it will almost reach the standard of earth veins."

"Didn't Liu Yan say that in order to destroy the war potential of the races on the ground, almost all the earth veins have been destroyed?"

"Is it possible that this deep part of the sea is a place where the demons have never set foot before?"

"But that's not right. Speaking of which, this place should still be within the scope of Qianxi Island, but it may be two or three thousand meters deep underground."

"Since the demons were able to destroy even the spiritual veins and dragon veins back then, there is no reason why they couldn't discover this earth vein!"

Frowning and thinking, Xiao Han did not stop moving for a moment, still waving the mining shovel vigorously, digging with excitement on his face.

"bite!"

But suddenly, a different voice sounded in his ears, causing him to stop what he was doing and shout with surprise on his face: "Fuck, no way!"
